The conducting resistance of MOS (Ron) depends on the width B and the length G of MOS raceway groove.Bigger width B causes littler Ron, and littler length G causes littler Ron.Through reducing Ron, can be increased in the number of times of MOS switch in section preset time, and therefore can obtain higher processing speed and the lower energy consumption of each switch events.
Yet when reducing Ron, if the width B of MOS raceway groove increases, the area of MOS possibly increase.The chip that the MOS area that increases can cause in equal area, having less computing capability, the bigger chip that perhaps has the manufacturing cost that is increased.Therefore, the area that reduces Ron and also do not increase simultaneously MOS is only favourable.
The technology of a kind of Ron of reducing comprises two basic MOS structures of ghosted, so that the drain region of each structure is overlapping, shown in the geometric figure of Fig. 2.According to this technology, effective width B is doubled (promptly existing each to have two MOS raceway grooves of width B), thereby has reduced Ron, simultaneously the gross area of this structure less than the twice area of single MOS structure (promptly less than the A of twice * B).Can repeat this structure as illustrated in fig. 3 to obtain even littler Ron.
The invention provides the geometric figure that is used for the MOS device, this geometric figure obtained device Ron's in addition further reduce, also do not increase the area of device simultaneously.

Embodiment
Fig. 4 is the diagrammatic sketch of vertical view of having described metal-oxide semiconductor (MOS) (MOS) structure of single MOS according to an embodiment of the invention unit (cell) 400.As shown in Figure 4, unit 400 is formed square shape, but in other embodiments, unit 400 can have round-shaped or any polygon polygonal shape, for example rectangle, hexagon or octagon.Unit 400 can be a MOS transistor for example, comprises NMOS and PMOS transistor, and unit 400 can be square DMOS (Square DMOS) (SQDMOS).Unit 400 comprises drain region 401, gate regions 402, source area 404 and 405 and the tagma 406 that on substrate, forms at least, and substrate for example is the substrate of silicon substrate or any other suitable type.
As shown in Figure 4, drain region 401 is formed square shape, but in other embodiments, drain region 401 can have round-shaped or any polygon polygonal shape, for example rectangle, hexagon or octagon.Drain region 401 comprises drain contact (contact) 409.As shown in the figure, show two drain contacts 409, but other embodiment can use the drain contact of different numbers, this part ground depends on action need, for example electric current needs.Drain contact 409 is spliced (butt) is used for given current capacity with optimization area.In an illustrated embodiment, the distance B 1 to D4 between drain contact 409 and the gate regions 402 is similar basically, but in other embodiments, distance B 1 to D4 can be different, and this part ground depends on the shape of drain region 401.
Gate regions 402 is around drain region 401.Gate regions 402 is formed on closed loop around the drain region 401, and wherein this closed loop has and the corresponding shape of the shape of drain region 401.As shown in the figure, gate regions 402 has square configuration, but in other embodiments, and gate regions 402 can have round-shaped or any polygon polygonal shape, for example rectangle, hexagon or octagon, and this part ground depends on the shape of drain region 401.Gate regions 402 can comprise the conduction or the semiconductive material of polysilicon for example or any other suitable type.Channel region 408 can be formed under the gate regions 402, and channel region 408 can be configured to make electric current to flow to drain region 401 from each source area 404 and 405.The gate contacts (not shown) can be attached to zone 407, and zone 407 is electrically coupled to gate regions 402.Zone 407 can comprise and gate regions 402 identical materials.
Source area 404 and 405, tagma 406 and zone 407 are disposed in around the gate regions 402. Source area 404 or 405 is disposed in each side of gate regions 402, and arrangement makes each side of drain region 401 equate or the source area of bigger width is aimed at (align) with having.In this way, the flow through electric current of raceway groove 408 can be maximized.Tagma 406 is disposed in around the gate regions 402 with zone 407, so that they are not aimed at a side of gate regions 402.Specifically, tagma 406 is disposed in the corner of unit 400, and wherein they can not be attached to gate regions 402 (with raceway groove 408), and zone 407 is arranged such that they can be attached to the part of gate regions 402.
Because tagma 406 is not arranged in source area 404 and 405 as in conventional MOS unit (Fig. 1), so the size of source area 404 and 405 can be less than the size of source area in the conventional MOS unit.
As shown in the figure, source area 404 and 405 is formed the shape of rectangle, and tagma 406 is formed square shape with zone 407.Yet; In other embodiments; Source area 404 and 405, tagma 406 and zone 407 can have round-shaped or any polygon polygonal shape; For example triangle, square, rectangle, hexagon or octagon, this part ground depend on shape and source area 404 and 405, the tagma 406 of unit 400 and regional 407 layout and/or shape.
As stated, zone 407 can comprise the gate contacts (not shown) that is electrically coupled to gate regions 402.Tagma 406 comprises body contact 411, and source area 404 and 405 comprises source contact 410.Can use in other embodiments with shown in the source contact 410 and body contact 411 of the different numbers in contact of number, this part ground depends on action need, for example electric current needs.
As shown in the figure; Shorter than the distance B between drain contact 409 and the gate regions 402 1 between source contact 410 and the gate regions 402 to D4 apart from S1; But in other embodiments, can be different apart from S1 and D1 to the relation between the D4, this part ground depends on puncture voltage.
Fig. 5 A is the diagrammatic sketch of vertical view of having described the array of four MOS unit 500 according to one example embodiment.Each unit all has the structure of the MOS unit 400 of Fig. 4.Unit 501 to 504 is arranged such that their source area 404 and 405 is overlapping.In this way, the gross area of cell array 500 can be less than four times of the area of individual cell 400.
Through arranging that thereby gate regions 402 makes it be looped around around the drain region 401, channel width can increase the gate regions part 510,511,520,521,530,531,540 and 541 shown in Fig. 5 B.Though some channel widths possibly lost, because under zone 407, possibly there not be effective raceway groove (promptly source area and drain region possibly not separated in zone 407), this loss can be less than the gain on the channel width.
In this way, the structure of MOS unit 400 (with MOS cell array 500) can have the littler Ron of Ron than conventional MOS unit (or cell array).Through gate regions 402 is looped around around the drain region 401, can increase clean channel width, and not increase the area of MOS structure.Through reducing Ron, can increase MOS switch number of times, and therefore can obtain higher processing speed and the lower energy consumption of each switch events.
Because the tagma is disposed in around the gate regions, so can not need the extra tagma around the source area.Because the tagma can not be included in the source area, so the size of source area can reduce.Through reducing the area of MOS, in area identical, more computing capability can be provided, perhaps can produce littler chip, thereby reduce manufacturing cost.
